In my line of work, its certain peoples' jobs to know certain things. If I need a piece of information that somebody else is responsible for understanding, I'm just going to ask directly for what I need instead of trying to research it myself. To research it myself would mean attempting to do somebody else's job, which is just unhelpful for everyone.
If its not just a matter of perspective and only medication can help, etc, then why do we call depression a "psychological" or "mental health" concern? Why isn't it just considered a neurological disease?
